RADIATOR FILLER-CAP.

Specification of Letters Patent.

Application filed August 9, 1919. Serial No. 316,292.

1 '0 all whom it may concern:

Be it known that I, CHARLES F. TAYLOR, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Radiator Filler-Cap, of which the follow ing is a full, clear, and exact description.

This invention relates to safety, appliances for caps or receptacles and has particular reference to filler caps for automobile radiators.

Among the objects of the invention is to so connect a cap to the filler neck as to provide for the quickest and easiest possible means for opening the neck for introducing water to the radiator.

Another object of the invention is to pro-- vide a means to make a permanent connection between the cap and radiator structure whereby any possibility of loss of the cap by carelessness or by theft will be prevented.

With the foregoing and other objects in view the invention consists in the arrangement and combination of parts hereinafter described and claimed, and while the invention is not restricted to the exact de tails of'construction disclosed or suggested herein, still for the purpose of illustrating a practical embodiment thereof reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which- Figure 1 is a front perspective view of a portion of a radiator showing my improvement attached thereto.

Fig. 2 is a vertical sectional view of the cap and neck on the line 2-2 of Fig. 3.

Fig. 3 is a vertical transverse section on the line 3-3 of Fig. 2.

Fig. 4 is a horizontal sectional detail on the line 44 of Fig. 2, the plane of the section coinciding with the plane of the contact between the lower edge of the cap and the upper edge of the neck; and

Fig. 5 is a sectional detail on the same plane as Fig. 2, but with the cap swung open.

Fig. 6 is an enlarged sectional detail view.

Referring now more specifically to the drawings 1 show a radiator 10 to which is attached a neck 11 of any suitable form in cross section, but having a permanent connection with the main portion of the radiator. The upper edge of the neck 11 is smooth and lies in a horizontal plane, but being preferably beveled as shown.

The cap 12. comprises a top 13 and a downwardly projecting flange 14. The top 13 may be of any suitable form or design according to the desire of the designer of the car so that the identity of the car being established more or less by the appearance Patented Nov. 1c, 1920.

of the radiator cap, the cap. need not be disturbed, although obviously any design of cap may be adopted in the spirit of this invention. The flange portion 14:, however, should preferably be designed to constitute a virtual continuation of the neck '11, it being preferably for this purpose of the same size and form as the neck and is provided with a smooth lower edge which lies directly upon the smooth upper edgeof the neck when the cap is closed, and a beveled shoulder between which and the beveled surface of the neck 11 there will be sufiicientspace or clearance to permit a limited movement of the cap with respect to'the neck. Any suitable-'means may be provided to connect the cap to the neck so as to swing the cap from its normal closed position around a vertical axis arranged at one side of the center of the neck so as to hold the cap in open position and yet maintain its connection permanently with the neck.

The means Iprefer to effect the connection between the cap and the neck includes a pivot lug 15 fixed to orformed as an integral part of the upper portion of the neck at one side thereof, the upper surface of the lug except as soon to be noted lying flush with the plane of contact between thecap and the neck. This upper surface of the lug, however, is provided with a notch 15' extending preferably along the top of the lug in a radial direction with respect to the radiator neck. The notch, however does not extend across the adjacent wall of the neck. In other Words the upper edge of the neck is continuous at the point 15 as well as elsewhere for two reasons soon to be made apparent. First, the continuity of the neck rim being unbroken, the appearance of the neck and cap structure is practically the same as the ordinary screw cap structure; secondlythe wall at 15 serves to assist in holding the cap in true centered position.

Obviously the hole 'l9 forn ed in the lug 1 8 and through which the pin projects must always register with the hole 17. Any suitable means may be provided to;lock the pin in 131306 1331501 instance a head on one end and bent over p01IltS at the other. Thepo nts indicated at 20 are shown as ly ngv in a notch El-formed in the ipper end or'surt'ace of thelug ,1 8 and atany desired distance below the top 13of theeap. V V

The lower surface of the lug 18 is provided with a projection 22 tormed as a counterpart of the notch 15, or substantiall-y so. Theouter end of the projection 22 bears normally against the inner surface of the wallsection 15 while-the lower stir-p face ori point of the projection extends, downward into thenotch under the force of fan expansion spring 23located between the V s the spring tending to hold the proj ection 22 ,in the notch 15 and theouter end of the projection snugly against the-inner surface of the rim section 15.

and prevent splashing of the water therethrough as well as to preserve the neat appearance of the structure. The cap may be swung around its pivot either by grasping it directly bythe hand or by pushing it by any other device if it is too hot to grasp with the-hand. The cap may be swung freely in either direction and from any position to any other position, except as inoderately resisted by the .force of the spring as described above; When the cap is swung around its axis the projection 22 riding up ,either side of the'V-notch, by cam action,

causes the lifting of the'cap automatically and hence requiresno thought or effort on the part of the operator tolit't the cap so as to cause it to clear the partsnormally holding it from rotation. v j

I claim: I In a device of the character sett'orth, the

combination of a neck having a smooth upper edge lying n a horizontal plane and a concentric beveled surface, a lug extend ing inward from the upper edge of the neck and flush therewith, but providedwith a at the outer edgeof the notch being continuous or unbroken, a cap having a downwardly projectingfiange and beveled shoulder meeting the upper edge of the neck there beinga limited movement between the said shoulder andibeveled surface, a lug carried by the cap and having a pro ection extending downward normally below the meeting plane of the cap and neck and constituting.

a counterpart 0i: said notch, the outer end of the projection abuttingnormally against the section of the wall .01 the neck at the outer. end of the notch, a pivot pin passing notch extending radially toward the center 7 of the neck, the wall of the neck, however,

through the lugs parallel to but at one side of the axis of ,theneck, and an expansion spring between one end ofthe pin and the adjacent lug, tending to hold the. projection seated inthenotchand the outer end of the 7 projection against the abutting wall. as
